Abstract

The invention provides a method for preventing and controlling citrus eriophyes oleivorus. The method comprises the following steps: 1, reasonable fertilization, i.e., applying an organic fertilizer to fruit trees, and applying nitrogen, phosphate and potash fertilizers through reasonable cooperation; and 2, coverage of orchard weeds and protection of natural enemies, i.e., planting shallow-rooted, short-plant, fast-growth and shade-tolerant grass seeds, wherein the grass seeds comprise ageratum conyzoides, white clover, medicago sativa or bean species crops; and through building a protection forest or a hedge around an orchard, setting a green barrier with a certain width; and 3, chemical prevention and control. The method provided by the invention can effectively prevent and control the citrus eriophyes oleivorus.

Description

The prevention and controls of a kind of citrus rust mite

Technical field

The present invention relates to the prevention and controls of a kind of citrus rust mite.

Background technology

In recent years, cumquat cultivated area increases year by year.The citrus rust mite occurrence degree of harm cumquat also increases and seriously accordingly.The yield and quality having a strong impact on cumquat of citrus rust mite.The control of citrus rust mite is also just most important.

Oranges and tangerines blister mite, insect name, belongs to Acarina, Eriophyidae.To cause harm citrus blade back and fruit.Thrust in citrus tissue with lancet and suck juice, make killed leaf, fruit oil vacuole break, overflow aromatic oil, after air oxidation, make pericarp or blade become dirty black.When causing harm serious, often cause fallen leaves and casting skin fruit, cause tree vigo(u)r weak.Become the long 0.1-0.2 millimeter of mite body, yellow-white, naked eyes are not easily shown in, have foot two right near head, and body body front portion is comparatively thick, and tail end is thinner.1 year more than 10 generation of life.High temperature and drought is beneficial to it and occurs.Particularly rainy season, rainfall was few, the generation of the very favourable citrus rust mite of high temperature and drought in June and procreation, and population quantity rises rapidly, and 7, August will occur peak of causing harm, some Citrus Orchard occurs fragmentary " ash fruit " " black fruit " etc.

Summary of the invention

The invention provides the prevention and controls of a kind of citrus rust mite.

The invention provides the prevention and controls of a kind of citrus rust mite, step is as follows:

(1), the rational application of fertilizer: fruit tree applying organic manure, nitrogen, phosphorus, potash fertilizer reasonable coordination are used;

(2), orchard weed covers and Protect natural enemies: plant in fruit tree the grass seeds that shallow root, plant are short and small, grow fast, resistance to shade in the ranks, and described grass seeds is: Ageratum conyzoides, butch clover, alfalfa or beans kind crop; Combine around orchard and build shelter forest or green Li, set up the green screen of one fixed width;

(3), chemical control:

Spray the lime sulfur of 0.8 ~ 1 Baume degrees when cleaning orchard in A, winter, to reduce insect density of surviving the winter;

B, when having wormed fruit rate >=3%, egg hatching rate >=16%, carry out daily control, the medicament used during daily control is as follows, each one selected wherein, and rotation uses various agricultural chemicals, and often kind of medicament uses 1 ~ 2 time for 1 year: machine oil emulsion 150 ~ 200 multiple; 73% propargite 2000 times liquid; 25% azacyclotin wetting powder 1500 times liquid; 5% Hexythiazox missible oil 2000 times liquid; 15% reaches mite missible oil 1500 times of liquid; 1.8% abamectin emulsifiable concentrate 3000 times liquid; 50% fenbutatin oxide wetting powder 2000 times liquid; 20% carbosulfan 1500 times liquid.

Method of the present invention can effectively preventing citrus rust mite.

Embodiment

Following embodiment is convenient to understand the present invention better, but does not limit the present invention.Experimental technique in following embodiment, if no special instructions, is conventional method.Test material used in following embodiment, if no special instructions, is commercially available.

embodiment 1

The prevention and controls of a kind of citrus rust mite of the present invention, specific as follows:

1, the rational application of fertilizer: fruit tree applying organic manure, nitrogen, phosphorus, potash fertilizer reasonable coordination are used;

2, orchard weed covers and Protect natural enemies: plant in fruit tree the useful grass seeds that shallow root, plant are short and small, grow fast, resistance to shade in the ranks.As Ageratum conyzoides, butch clover, alfalfa, beans kind crop etc.; Combine around orchard and build shelter forest or green Li, set up the green screen of one fixed width.

3, chemical control:

Spray the lime sulfur of 0.8 ~ 1 Baume degrees when cleaning orchard in A, winter, to reduce insect density of surviving the winter;

B, when having wormed fruit rate >=3%, egg hatching rate >=16%, carry out daily control, the medicament used during daily control is as follows, each one selected wherein, and rotation uses various agricultural chemicals, and the resistance delaying citrus rust mite produces.Often kind of miticide uses 1 ~ 2 time for 1 year: machine oil emulsion 150 ~ 200 multiple; 73% propargite 2000 times liquid; 25% azacyclotin wetting powder 1500 times liquid; 5% Hexythiazox missible oil 2000 times liquid; 15% reaches mite missible oil 1500 times of liquid; 1.8% abamectin emulsifiable concentrate 3000 times liquid; 50% fenbutatin oxide wetting powder 2000 times liquid; 20% carbosulfan, 1500 times of liquid etc.

Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
